Abstract
An electric toothbrush is disclosed. The toothbrush includes a handle part and an attachment part, wherein the handle part has a housing, in which a reservoir for a care substance, a pump for delivering the care substance and a drive unit for driving the pump are arranged. The housing is divided into a liquid-tight first chamber and a second chamber by a partition extending in the longitudinal direction of the housing. The first chamber housing the drive unit is arranged in the first chamber and the reservoir and the pump are arranged in the second chamber.
Claims
exact text as granted — not AI-modifiedWhat is claimed is:
1. An electric toothbrush having a handle part and an attachment part, wherein the handle part has a housing, in which first and second reservoirs for care substances, first and second pumps for delivering the care substances and first and second drive units for driving the first and second pumps are arranged,
wherein the housing of the handle part is divided into a liquid-tight first chamber and a second chamber by a partition extending in the longitudinal direction of the housing, wherein the first and second drive units are arranged in the first chamber and the first and second reservoirs and the first and second pumps are arranged in the second chamber.
2. The electric toothbrush according to claim 1 , wherein the partition has a liquid-tight slide passage and the transmission of a driving movement (A′-B′) from the drive unit to the first pump takes place by means of the slide passage.
3. The electric toothbrush according to claim 1 , wherein the partition is partially designed as soft-elastic, and the transmission of a driving movement (A′-B′) from the drive unit to the first pump takes place in the soft-elastic region of the partition.
4. The electric toothbrush according to claim 2 , wherein the transmission of the driving movement (A′-B′) from the drive unit to the first pump takes place via a lever.
5. The electric toothbrush according to claim 1 , wherein the attachment part is connected via a canal to the first pump and the first reservoir.
6. The electric toothbrush according to claim 1 , wherein the attachment part is drivable by a drive unit that is arranged in the liquid-tight first chamber.
7. The electric toothbrush according to claim 6 , wherein the drive unit for the attachment part and the drive unit for the pump are arranged in the first chamber, one behind the other in the longitudinal direction of the housing.
8. The electric toothbrush according to claim 1 , wherein the first and second reservoirs are designed with a low-profile shape.
9. The electric toothbrush according to claim 1 , wherein the first and second pumps are diaphragm valve pumps.
10. The electric toothbrush according to claim 1 , wherein the first and/or second reservoir consists essentially of a plastic foil.
11. The electric toothbrush according to claim 10 , wherein the first and the second reservoir are arranged side by side.
12. The electric toothbrush according claim 1 , wherein the pumps are connected to a coupling part for connecting the reservoirs.
13. The electric toothbrush according to claim 12 , wherein the coupling part has an inlet valve that is activated by connecting the reservoirs.
14. The electric toothbrush according to claim 1 , wherein the first pump in combination with a first inlet and with a first outlet that is connected via a first canal forms an assembly or that the first and second pump in combination with a first and second inlet and with a first and a second outlet that are connected via a respective first and second canal form an assembly.
15. The electric toothbrush according to claim 1 , wherein the two reservoirs are filled with different care products.
16. The electric toothbrush according to claim 1 , wherein the second chamber has on its outside a recloseable cover part.Cited by (0)
